Admission to McGill: Desautels or Science

Thanks in advance for any advice provided. My son is interested in studying finance/economics at McGill. Two routes come to mind, the BCom at Desautels or the BA in Economics. What are his chances of admission to either option given his grades:
-GPA: weighted = 4.2; unweighted = 3.7
-AP courses: Calc BC (4), Physics C (5), MicroEcon (?), Comparative Government (?), Computer Science (?)
-SAT: 1360 (Read/write 630, Math 730)
-SAT2 math: 790
-ACT 29: 35 math, 30 science, 24 English, 26 Reading

Assuming that you are American, here are the minimum requirements for 2019:

Desautels would be a reach if not out of reach. Arts would be a high match.
Note that economics is in the Faculty of Arts, not Science.
